Re: [gem5-users] 回复： Installing Shared Libraries to Image in Full Simulation

[Abhishek Singh]

Hi,

This is the i got in past when I was trying to run SPEC in SE mode

If you check mailing list there are suggestions about it

I have not yet ported the spec 2017 to gem5, I was trying to use FS but
then I saw that 03 CPU in gem5art shows unsuccessful

I am planning to port spec benchmarks in coming weeks

If you or ANYONE have already posted SPEC 2017 benchmarks for O3CPU please
share your knowledge and steps ?

HiAbhishek,
 I am running the spec 2017 in the gem5 
simulator(X86). But a lot of benchmarks didnt works.
 It shown tha :
 warn:instruction 'movntdq_Mo_Vo' 
unimplemented.
 So,what I do for it?

  And anyone can tell me how to deal with it? Thank you.

On Sat, Feb 8, 2020 at 5:42 PM Ayaz Akram https://gem5art.readthedocs.io/en/latest/tutorials/boot-tutorial.html;


and if you go through the disk creation process in that tutorial, you will 
realize that there is a post installation script that runs on the disk image 
after its creation 
(https://github.com/darchr/gem5art/blob/master/docs/disks/boot-exit/post-installation.sh).
 In that script, the contents of exit.sh 
(https://github.com/darchr/gem5art/blob/master/docs/disks/boot-exit/exit.sh) 
which are written to/root/.bashrc are responsible for exiting the 
simulation as soon as linux is booted.


One thing you can do to avoid exiting the simulation after linux is booted is 
modify the /root/.bashrc  in your disk (after mounting it on your file 
system.) Or you can modify the post-installation.sh and create a new disk 
image. Another thing you can do is modify your fs.py to call m5.simulate() 
again when simulation terminates the first time (following the m5 exit call 
from .bashrc).


Hope this helps.

As far as I know, it is not going to be possible to use this for other cpu

 Hi Ayaz,

 Thanks for providing the image and kernel, I see on gem5art test
 results that the image can support at the most only one cpu for O3CPU 
 model.
 Is that still the case ?
 I wanted to use this image for running multithreaded applications on
 x86 O3CPU FS mode.

Hi Abhishek ,

Can you run it with PACKER_LOG=1 as suggested? The output may help to solve
the problem. I remember that I was also having a similar problem. I found
the solution by adding my user to the kvm group or running with sudo. That
might also be the case for you.

Best,
Muhammet

[gem5-users] [ARM se Ruby] Page fault with SPEC CPU 2006 for ARM ISA

[Carlos Escuin]

Hi,


I'm trying to execute the SPEC CPU 2006 benchmark on multicore, ARM, se. 
However I'm having this problem:


   panic: Page table fault when accessing virtual address 0x11


So far, I have read that the problem may come from the cross-compiling 
of the SPEC benchmarks.


Any hint in which cross-compiler to use / which flags to set?


Thank you

Carlos

Re: [gem5-users] Commit numbers/tags of previous stable version missing

[Jason Lowe-Power]

Hi Abhishek,

In the relatively distant past (e.g., 6+ years ago), we marked a few
commits with "stable" tags. However, these commits were no more stable than
any other. It was completely arbitrary. I would not trust these commits any
more than any other random commit 6 years ago.

At that time, we did not have any formal processes in place for stable
versions of gem5. This is changing with gem5-20. Importantly, gem5-19 also
is not any more "stable" than any other commit. gem5-19 is only being used
for us to *test* these processes.

Cheers,
Jason

I want to simulate the bus invert method between L2cache to L1D Cache.

But Learning-gem5 or tutorial is not supported this.
Through Commmonitor, I can trace the bus between L2Cache and L1DCache, but did 
not know how to apply the bus invert method.
can you tell me which part modified for Simulating Bus Invert method
